2' k2 all is how it may concern:

Be it known-shot i, YR-torrent) LA FRANCE. arityizen oi theUnited States, residing; at iioledo, in the. county of Lucas and fotate of (lhio have invented new and useful improvements in (Hess-Cutting Mechanism, of which the following is a specification.

My invention relsies to apparatus for cutting niolien or pissiie loss, and as herein shown is particularly sfiepted for'severing the glass in e, suction mold from the body of nuiiten glass from which the charge in the niohi has been gaihered.

An object of the inveniion is to provide s simple and preciical construction for the purpose stated, wherein the cutter may be assumed by a piston motor, ihe latter operating the cutter through suitable speed rouliiplying gearing. whereby quick and positive action or the iznii'e is obtained. A further :ifeaiure of (he invention relates to improved .nieuns for giving the knife a downward movement away from the mold before it'is withdrawn after the cutting stroke.

(hhcr feetures and advantages of the invenaion wiil appear hereinafte This application is a division of my copenriim eppiicerion Eerie} Number 189,4;33"

detail view of the brought successively to gathering gosiiion the cutter to the lucid and ga'd'ierover the tank 12. Each mold as is brought over the tank is lowered into concoct with -the molten glass in the tank and the glass drawn by suction into the mold. The moid is then lifted'to the Figure 3 position and. e .cuiter blade 13 carried on an arm 14- is projected horizonielly to ihe position shown in full lines in Fignre 3, and fiherehy severe the glass in the mold from the shrin of glass which extends from the mold to t is pool as the moid is lifted. Aim this operation the knife is :oved veriiceliy downward so the broken line posision in i igure 3 before it is wizhdrawn horizontally.

The knife arm 14; is scene-e ed by a piston motor 15 operating throu h the following meehenism: A pisoon re 16 of the motor is attached to 'a rock 17 in mesh with e pinion 18 on a shaffn 19. m which is secured a gear 20. ihe letter drives e pinion 22 on with a rack 25 in which the knife arm 14:

is secured. When fluid pressure is admitied in front of the motor pision the hitter is driven to the right, and through the train of feers just described operates to shoot the dude 13 forward to the operative position shown in broken lines in Figure 1, thereby severing the blank or charge of in the mold from the gioss in the tanks-rid closing the gathering openiu in she bottom of the mold. Before the his is is wiihdrown it is given a. short vertical downward movement by the following inechsziism:

A stationary cam 30 on the mochihe frame operates through a cam roll 31, vertical rod 32 carrying said roll, rock arms 33 {frid e on :i sieeve 35, and verticei rod 36 to lift e frame 37 in which the rack her 25 is slidably mounted. The frame 3? is mounted for r I verticei sliding movement on the frame 38. 'ihrouggh the connections just described, the can: 30 by depressing the roli 31 iifts the cuiter. The com is so positioned that the knife is lifted before being shoiforward to sever the glass. The roii 31 runs 05- the com to eiiow the cutterto drop before iswithdrown horizontsiiiy. the weight, of the "frame 37 and ports carried therewith being sufiicient to insure such drop.

The cutter is adjustable up and down by means ofo hand wheel -10 on a horizontal shah; joiirnellcd in the frame 37. said shaft carrying e. bevel inion .1 is. mesh with .ZL

. the spiri zbevel geaz" having a screw threaded connection with the re; 36. i-Vlien "the hand wheel is rotated the FOG, 36 is moved up or clown in the gear 42, thereby adjusting; the knife up or down.

Modifications may be resort to wiolzin and seope of my inven'ion.
